If your mopar is you daily driver!
My '74 is my daily driver at about 17mpg combined. Mileage isn't great but driving an old car is incomparable.
Having owned many different types of vehicles, I've learned that there is no free lunch as far as fuel economy goes. You can drive a 4-banger and get good mileage, but on the other hand it's a belly-button car that is mostly good at carrying people.
If you need a truck you can get a mini-truck but they can't do serious work, and by serious work I mean towing cars and hauling 5k of cargo.
If you DO need a serious truck then you are back to getting low teens fuel mileage and in most people's cases making BIG payments because they just can't imagine driving something old.
So, it's a trade-off. I have 3 mopars with a 4th on the way, a paid-for 20yo diesel truck and a belly-button that I drive when it's bad out or I'm someplace where the old car might get lifted. I don't make payments and I stopped worrying about gas mileage long ago.
